- Abstract
- (en) The multimodal freight network models are traditionally based on the four stages ap-proach in which generation, distribution, modal split and assignment are seen as separated modules. An alternative approach is to represent the multimodal network by a service net-work, in which each transport operation (loading, unloading, transhipment, ...) is repre-sented by a dedicated "virtual link". In such a network, modal choice and assignment can be combined in a single step. This approach, adopted by several authors and known as "super-networks" or " virtual networks" gives interesting results, but requires dedicated assignment methods, which have to distribute flows from an origin to a particular destination over several alternative routes. It comes out that equilibrium assignment techniques are not appropriate when they are used for long haul trips and when only aggregate data on the demand is available. Indeed, the obtained results appear to be very close to an All-or-Nothing assignment
